Maintains the edge strength at the corner and prevents suddenfractures. Flank f (IPR) VBMT221FM Recommendation for finishing carbon steel, Carbon Steel·Alloy Steel Corner alloy steel, mild steel and stainless steel Suitable for low depth of cut and feed rate applications. Sharp cutting edge and low resistance design provide excellent cutting Flank performance. f (IPR) VBMT221FV Finishing difficult-to-cut materials Difficult-to-Cut Materials Corner The curved cutting edges support changes in cutting depth, smooth chip discharge and disposal. Flank The high rake angle is highly suitable for finishing difficult-to-cut materials. f (IPR) VBGT330.5FJ Finishing titanium alloy Titanium alloy Corner Ideal for aluminum and copper. The sharp edge produces excellent surface finishes. Flank The curved edge allows smooth chip discharge. The polished insert face prevents built up edge. f (IPR) VBGT330.5FJ-P Finishing carbon steel and alloy steel Carbon Steel·Alloy Steel Flank Angled chipbreaker controls chip flow. Sharp cutting edge produces excellent surface finishes. f (IPR) VBGT221RF LP Recommendation for light cutting of carbon andalloy steel Carbon Steel·Alloy Steel Corner18° Sharp cutting edge due to a high rake angle.Prevents chip welding on cutting edge and controls cloudiness of surface finish. Flank8° Chip breaker peninsula matched to depth of cut capability provides excellent chip control. f (IPR) VBMT221LP LM Recommendation for light cutting of stainless steel Stainless Steel Corner18° Sharp cutting edge due to a high rake angle.
